Mean Actual Breastfeeding Duration by Prenatal and Neonatal Intention (N = 1,780), IFPS II, 2005–2007

Prenatal intended breastfeeding duration	Change in intended breastfeeding duration at neonatal report	n	Mean prenatal intention (months)	Mean neonatal intention (months)	Mean actual breastfeeding duration (months)	P-value^a

≤6 months	Shorter	151	5.0	2.7	3.4	<.001
(≤26 weeks)	No change	184	5.3	5.3	7.1
	Longer	149	4.2	8.0	8.0
>6 months	Shorter	472	12.2	8.3	10.3	<.001
(>26 weeks)	No change	594	12.9	12.9	13.5
	Longer	230	11.6	14.7	13.6

P-value was obtained by Wilcoxon signed rank test comparing the mean ranks of actual breastfeeding duration by change in intended breastfeeding duration at neonatal report.
